Abstract

The invention discloses a gas detection device for a GIS chamber. The device comprises a shielding case, a micro-processing chip, an analog-to-digital conversion module, a sulfur hexafluoride sensor and a display module, wherein the sulfur hexafluoride sensor is arranged on an inner side of the shielding case, a detection port of the sulfur hexafluoride sensor is arranged on an outer side of the shielding case, an output end of the sulfur hexafluoride sensor is electrically connected with an input end of the analog-to-digital conversion module, the analog-to-digital conversion module is arranged on an inner side of the shielding case, an output end of the analog-to-digital conversion module is electrically connected with a first input end of the micro-processing chip, the micro-processingchip is arranged on the inner side of the shielding case, a first output end of the micro-processing chip is electrically connected with an input end of the display module, and the display module is arranged on the outer side of the shielding case and fixedly connected with the shielding case. The device is advantaged in that the sulfur hexafluoride gas concentration in the GIS can be detected inreal time, and if the sulfur hexafluoride gas concentration exceeds a threshold value, a sound alarm is given to remind a worker.

Description

technical field [0001] The invention relates to the field of gas detection, and more specifically, to a gas detection device for a GIS room. Background technique [0002] The full name of GIS is gas insulated fully enclosed combined electrical appliance, which is an important equipment in the power system. Because of its high sealing performance, it is widely used. The GIS cavity is filled with sulfur hexafluoride gas. Sulfur hexafluoride gas itself is not toxic, but it will decompose a variety of harmful and combustible gases (such as carbon monoxide, acetylene, methane, etc.) under high temperature and discharge conditions. Generally, GIS equipment is installed in a closed room, and electrical test and inspection personnel will conduct periodic surveys and tests on the GIS room. If a gas leak occurs, it may lead to catastrophic consequences in a sealed environment. The current GIS room is equipped with a hair dryer, and personnel need to ventilate for a period of time be...
